Are the crew + 6.5 standard box having issues too?

Yes. Any cab and bed configuration, engine, transmission, gear ratio, trim package, etc. are having issues. Seems to be more prominent in extended and crew cabs though. There have also been reports of a few HD trucks that are having issues as well

yes, from what i have read and two of my friend's have that config with 6.2's both not happy but different vibrations than the rest of us complaining about. others in this thread have said their 6.5 CC have vibrations above 70 so it's again, something cumulative not a singular issue which is why WE ALL BELIEVE IT TO BE AN ENGINEERING/DESIGN FLAW that's why even when it's "fixed" it doesn't completely go away, just changes to intermittent and/or different load/speed noticeable

 

i have said it before i'll say it again... maddening... trucks are so nice, quiet, ride great at under 55mph look great and BAM cannot go on a hwy cruise.. the main reason we bought the truck is to have the full size truck RIDE we have become accustomed too having owned so many.. never this issue.. closest was a set of tires/wheels improperly balanced..

I was hoping the issue would have been fixed with the refresh. A bit gunshy to pull the trigger now.

I was also hoping the issue had been found. My 2014 Sierra has 31000 miles on it. At 25000 they rebuild the rear end put 4 new tires on a replaced the rear shocks. I can hardly notice any vibration but sometimes I swear I can feel it. I would call mine 99% fixed. However I believe there is one more missing piece to this puzzle. I keep checking in to see if it has been found.

 

I would probably not buy another 1500 GM until this issue is found. I will either go 2500 or go with another brand Or thoroughly demo a new truck and make sure there is no shake. All the loaners I were given had it too to a varying degree.

 

Good Luck guys.

Kind of hard considering mine didn't develop till 15k, and I believe that's the highest mileage on here. Mine is not as bad as many others on here, so mine could honestly just be tires. Need new ones anyways, maybe it will fix it. If not, I just spent money on tires on a truck I'm not gonna keep lol

Now that I'm thinking about it, people are having the same issue of varying degrees at different speeds. I wonder if something internal of the motor or trans is out of balance, like let's say the crankshaft possibly? As far as why it may come and go, you got me there lol

My thought was the torque convertor or inside the transmission.

But it could be any rotating part inside the engine or transmission.

If it was the engine or flywheel it would do it in neutral and rev the engine up.

So, 5.3's do it, 6.2's do it, 6 speeds do it, 8 speeds do it, Z71's do it, LT's and SL's do it, different gear ratios do it, steel wheels or alloys do it. What is common to all of these trucks? From the front: Wheel bearings?, cv axles?, brakes?, struts (springs anyway)?, Transfer case(?), drive shaft?, rear axles and bearings?, rear ends?, rear brakes and springs.? are six cylinder guys having the same issues? I am intersted to see what the non road test, wheels off the ground results will be. I know my suspension pics up every crack in the road so, i am willing to bet that anything could be causing this right down to buffeting the underside of the truck and transferring through the cab. but then, i am just guessing

Your 2016 vibrates?

yes, I have the V6 and have it too

mine isn't 2016, but i have seen a few reports of 2016's vibrating

Ok. So are we thinking the same thing here? Not engine, not transmission, but is a rotating component? Which leaves front and rear axles and drive shaft. Could it be amplification of a problem through the stiff suspension? I guess with all of the different vibrations called out, i will stick with the 65-80mph one lol.

 

Also, if it isn't in the steering wheel, can it still be in the front end?

    • I’m definitely interested to hear the end result here. 
    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
